During the boom times for the glass industry, some moulds were carried to several different companies by glass makers that worked for both companies. In addition, it wasn’t unusual for orders to get filled by another company if one was too busy. Then when companies started closing the moulds started moving again. Consequently we have found that etches, cuttings, and blanks moved around. Add all that to special runs for stores and decorating companies and you get diversity and confusion. There was also a lot of experimentation as well as end runs of glass being used on other moulds.
This ongoing project currently does not list many of the internal movements of company moulds in the larger glass corporations that started to emerge during the early part of the twentieth century. After their initial start up many companies became part of larger glass corporations which often also meant the moulds became part of a new parent company. We have attempted to document the final resting place of the moulds used by the American glass companies which with the exception of Fenton have now all expired.
Bartlett Collins closed in 2004 molds went to Anchor Hocking
Beaumont molds were bought by Fenton.
Bryce molds went to Lenox
Cambridge molds were bought by Imperial. Many of them went to Summit Art Glass and many went to the National Cambridge collectors when Imperial closed. In 2006 Cambridge Collectors were able to purchase all of the Cambridge moulds from Summit Art Glass.
Central molds were bought by Imperial. They went to the National Cambridge collectors when Imperial closed.
Consolidated molds were bought by Phoenix.
Cooperative Flint molds were bought by Phoenix.
Davies molds were bought by New Martinsville.
Dugan became Diamond and molds eventually went to Fenton.
Dunbar molds went to Weston.
Duncan Miller went to US Glass and Indiana Glass, then to Fenton and then went to Viking and finally Lenox.
Federal went bankrupt and out of business in 1977 or 1978 and all of its molds went to Indiana Glass.
Fenton evidently sent some of their molds to Viking in the 1950s.
Fostoria molds were bought by Lancaster Colony then by Fenton circa 2004. They have already reproduced the rooster in their periwinkle blue.
Fry molds were bought by Libbey
Hazel-Atlas changed owners and it's name first to Hazelware and finally to Brockway Glass
Heisey molds were bought by the Heisey Collectors of America.
Indiana became part of the Lancaster Colony which was also the parent company of Tiara which produced glass for that company. Fenton bought most of the molds Indiana had upon closing including the Fostoria ones but most were unuseable.
Lancaster molds are still with the parent company, Anchor Hocking.
Liberty molds appear to have gone to Cambridge.
Mac Beth-Evans molds were bought by Corning.
McKee molds were bought by Jeannette which explains why those pesky scalloped ones keep showing up where you don't expect them).
Monongah molds went to Anchor Hocking which was their parent company.
Morgantown molds were bought by Fostoria and then they went to Bailey but eventually went to Schott.
National molds went to Anchor Hocking.
New Cumberland molds were bought by U.S. Glass
New Martinsville became Viking.
Northwood molds went to National then to Dugan/Diamond then to Fenton.
Paden City molds were bought by Canton, Fenton, and Viking. However New Martinsville and PC were always trading workers, as their factories in close proximity to each other. One wonders why Viking (who was New Martinsville) bought the moulds, perhaps the close relationship was only in the early years.
Phoenix is now part of Anchor Hocking Industrial Glass, and no longer makes art glass.
Standard molds are still with the parent company, Anchor Hocking.
Tiffin/U. S. Glass Some of their molds may have gone to Anchor Hocking which was made up of at least 14 companies, so one assumes those molds moved around. Fenton got their rabbit lamp and Rose candlesticks.
Viking Some of their Janice molds went to Mosser.
Vineland. became Kimble and still exists.
Weston, Louie, and West Virginia Glass Specialty were all eventually owned or managed by the Wohinc Family. They existed in some form through the early 1970s as Princess Glass which was sold in home parties. The location of their molds is unknown.
Westmoreland molds went mostly to collectors but their Panelled Grape and perhaps others went to Fenton.
Anchor-Hocking, Kopp, Lenox, Libbey, Louie, LE Smith, and Schott still operate under their own names.
I have no idea what happened to, Brockway, Canton, Jeannette and Jenkins molds.
Sadly, regardless of where the molds ended up many of them have not been properly preserved and are now unusable. In addition moulds produced for hand work are not acceptable for machine made operation
